Nand2Tetris course is starting on Coursera

March 30, 2015

0

Nand2Tetris is a famous learning resource that teaches computing from the ground up, where the bottom brick that is used to build anything is the digital NAND port. It teaches the basics of Hardware Description Languages (such as Verilog and VHDL), and applies it to build a processor. It then guides into writing an assembler […]

An example of CPU for FPGAs

August 11, 2012

MyHDL is a Hardware Description Language based on Python. Last year I packaged it for Ubuntu Karmic Koala (here the blog post) and put it on my Launchpad Personal Package Archive (PPA) in order to be installed by everyone. Today I ported MyHDL 0.6 to Ubuntu Lucid Lynx; to install it, run from the command […]
